Anunnaki
The Anunnaki are higher dimensional ethereal beings from the star system sirius they are the Elohim and they created this 3rd dimension. These ethereal beings are crystal angels from the 12 vibrational dimension and higher, these beings are split into 3 empires, the Xenplexian empire, the RA Confederacy+the Lyrans and the Anu empire(Anunnaki empire), these empires colonized certain energy points that matched their energy signature. Some of the Anunnaki are reptilians whilst the Xenplexians containing Anunnaki DNA and Martian(orion-anunnaki reptilian) DNA are a amphibian(mammalian-reptilian) race themselves.
The Orion-Anunnaki reptilians are divided into two types, the Elders and the Tiamatians.
Tiamatians
According to some researchers, the Reptoids which evolved on Earth in the Cretaceous period were not the original race, but were seeded by a far more advanced race of interdimentional reptile beings known as the Tiamatians.
Elders
The most ancient of ancients are the royal/elite line of Reptoid that have wings. They range from 14 to 22 feet tall (~ 4.2 to 6.7 meters) and can weigh up to 1,800 pounds (~ 816 kg). Their appearance is what may have inspired dragons, angels, demons and devils in mythology and folklore.
Martians
This race of reptilians are descendence of the Orion-Anunnaki reptilians.
Greys
The Greys/Grays, are self-replicating liquid metal hivemind from the lower octaves of the 4th dimension that require DNA to replicate and, are originally known as the Solipsi Rai who are a benevolent and curious race, when not indoctrinated. They are thought to be more helpful in humanity's spiritual progression. The Anunnaki are known to have genetically modified the royal line of Greys, known as Zetas, with the Human template to look more Human.
The relationship between the draconians and the Greys is very strained as the Reptoids, on their goal of conquering planets, have enslaved the Greys, genetically modified them with draconian DNA to infected a portion of the hivemind with nubilus energy, and inducted them into the Orion program to create the Greys who are known as Orion Greys who are under the direction of the illuminati draconians and often engaged in abductions, to extract human DNA (to self replicate), and experimentations.
Saurians
The Saurians have ties to Human history and have influenced Semitic script. They have been living amongst Humans since the beginning of their inception. Millions of years ago Saurians looked more crocodilian and had defensive tails. As they evolved, they became more Human-like, many having lost their tails, and some even developing hair follicles (mainly on the scalp). Their evolution has not only made them intelligently superior, but also telepathic.
Vampires
Vampires are a species of semi-humanoid reptiles.
Draconians
The Draconians are Orion-Anunnaki reptilians that became nubilus (ethereal) beings, these beings are lead by one of the original rulers of the Anunnaki empire who is known as Enlil(Satan), most of these beings were originaly the martian(Orion-Anunnaki) race. These anunnaki became the hostile Draconian Empire. They have also been known as the Cekahrr; also spelled Ciakar.
These sinister creatures are literally sustained by the fear of the races they have subjugated, and that they particularly enjoy feeding on children. Additionally, they have been described as a hive-based society, with the warriors being ruled over by a seldom-seen elite caste which never leaves their capital world. This elite is sometimes depicted with wings, similar to the aforementioned Elders.
Like their ancestors, the Draconians typically operate from subterranean outposts, and are masters of conquering worlds by secret manipulation of figureheads.
